Job description

We serve investors, traders, and quants with a platform to design investment strategies. They code up trading strategies and test them on historical data. When they're ready, they can live trade on their brokerage.

Under the hood, we curate and update hundreds of terabytes of data — covering financial data (e.g., stock prices, options prices), fundamental data (e.g., PE ratios, company debt), and alternative sources (e.g., news articles, sentiment). We have a powerful data processing stack that handles ingestion and distribution of all this data to our different consumers.

Note: We have a slight preference for UK/Europe applicants so you're awake at 4 am ET, long before the markets open.

Responsibilities

We're seeking a full-time, mid to senior C# engineer to manage, maintain, and expand our data stack. Your responsibilities include:

• Monitoring existing data infrastructure (historical processing, daily updates, live feeds).
• Debugging and improving data infrastructure as needed.
• Responding to user reports of data issues and patching data.
• Collaborating with third-party vendors to source data for gaps.
• Onboarding new data sources to enrich our content for strategies.

Required Skills

• Strong proficiency in C#, Linux, .NET, OOP coding, and Python scripting.
• Experience with enumerable, streaming code design, efficiently handling terabytes of data.
• Comfortable with the high-stakes, on-call nature of data engineering.
• Meticulous attention to detail to quickly identify data issues.
